Looper Provider with an ACF field in the query

[pvallaeys]

Hi,
I am trying to build a looper provider giving me all the posts that have a specific tag. Lets say “music”. Works perfectly using the Looper Provider Query Builder putting music in the taxonomies. But now I need to find the posts that have the tag (e.g. music) in an ACF field (e.g. requested_tag).
Putting {{dc:acf:post_field field=“requested_tag”}} in the taxonomy field of the Query Builder does not work.
I have been trying all kind of other ways to get this working, but nothing works. Am I missing something or do I have to use a different approach?
Thank you for any help you can give me,
Patrick

Hello Patrick,

Thanks for writing to us.

Do you have created the tag using the ACF or it is just a post-meta field? In case you want posts that have a specific meta field value, I would suggest you set the looper provider as a Query string.
Please have a look at this article to learn more about how to use query strings.

Hi @wowflak, You need to create the meta query using the meta_key to specify the field name instead of the category. You need to mention the meta key in your Query String and that might look like that. Your main query should look like that. $meta_query[] = array( 'key' => 'artist', 'value' => '{{dc:acf:post_field field="artist"}}', 'compare' => '==', ); $query = array( 'post_type' => 'releases', 'meta_key' => 'artist', 'orderby' => 'meta_value', 'orde…

I actually found how to do it before I saw your reply, but thanks anyway.

I was talking about a search in the meta, not an ACF field. The ACF field is the tag I am looking for. So here is what finally worked. A Looper Provider Query String:
order=DESC&tag={{dc:acf:post_field field=“show_posts_with_tag”}}

Now my next question is how to exclude the current post if it has that tag I am looking for.
I tried the following, but it did not work:
order=DESC&tag={{dc:acf:post_field field=“show_posts_with_tag”}}&post__not_in= {{dc:post:id}}

Any hint?

Hi Patrick,

The {{dc:post:id}} will give the current post id, irrespective of whether the tag is attached to it or not, and will exclude the current post from the Looper output. But you are trying to exclude the current post if it has that tag, which is not possible.

Thanks

Yep, that’s right, but it doesn’t matter as the current post will not show up if it does not have the tag anyway as the looper provider only gives the posts that have the tag.
The problem is that post__not_in= {{dc:post:id}} does not work. The current post is not excluded. I found out this morning that post__not_in expects an array. This allows to exclude multiple posts. But {{dc:post:id}} is not an array. Can you think of a work-around?

Hi Patrick,

You can get more details on the post__not_in in the following thread.

Howdy, @dajanorganics! Thanks for writing in and sorry for the confusion here. I’ve checked with @alexander on this and asked him to take a look at things to see what the status might be on this feature. It is possible that the final implementation did not get rolled in to this last release due to various reasons, but we definitely plan to have something in for it down the road. That being said, I wanted to get you a working bit of code for the time being to help tide you over. To do this, I us…

Hope it helps.
Thanks

Great. That worked. I don’t understand how we get from
‘post__not_in’ => array( ‘{{dc:post:id}}’ ) to the syntax
post__not_in%5B0%5D={{dc:post:id}} as the %5B0%5D translates to [0] if I get this right, but it worked, so I am happy.
Thanks a lot! I always appreciate your responsiveness.
Patrick
